Lines and polylines are basic objects that consist of one or more straight line segments.

Lines

A line is a single line segment, and has a color, a line style, and line endpoint styles, and belongs to an overlay. To draw a line, select the line tool . Then for each line you wish to draw, click the left mouse button at one endpoint, hold down the button while drawing to the other endpoint, and release the mouse.

Polylines

Polylines are lines with multiple segments. A polyline has all the properties of a line, and may also have a fill color and pattern. To create a polyline, select the polyline tool . Click on the first and each successive point of the polyline. When you are finished, right-click and choose Create Open Figure or Create Closed Figure. You can use Backspace to remove the last point you've placed of a polyline before you've finished it.

Polylines come in three flavors. Open (far left) polylines are just like multiple segment lines. Closed polylines can either have a fill color and pattern (right) or can be empty (middle), depending on the Fill Color button. Click the second button on the color toolbar and choose No Color for empty; otherwise, choose the color you want to fill with. Click the third button on the color toolbar to set the fill pattern. The Fill Pattern (in this case bricks) will be a combination of the main color (black) and the fill color (red).
Whereas open figures have an arbitrary starting and ending point, in closed figures, the start and end points coincide.

While a polyline is selected, there are two additional actions that other objects do not have. You can use Alt while dragging a handle to create an additional vertex at that point (similar to the Scalpel tool). And you can remove a vertex by dragging its handle over an adjacent handle (like the delete function of the Scalpel).
